    That’s great Jeff, I’ll look forward to meeting you. We may be segregrated to a politically correct section in the back or maybe even outside the presentation room!

    Al,
    It’ll be be nice meeting you.
    I’ll be working the Booth with Millennium during the Tech Exhibits, so I’ll be around all weekend.
    See you then.

    Well,

    It looks like Canadian clearance is winning out over ADA.  

    Del is staying home to work on it due to motivation by guess who?cool.gif

    But those who haven’t met Janie DeMatteo–MDT’s Business Manager–really should go by the booth and say hello.  She’s managing the booth along with Rusty.:):)

    If MDT makes more sales that usual, Del is staying home for good and Janie’s on the road from then on………..

    Dr. Douglas Dederich lecture was interesting .
    In light of my new policy of trying not to piss anyone off thats about all I can say.

    David: was it confrontational with disagreements from the audience or was it a passive affair with alot of non laser users smiling because someone kept telling them that lasers werent needed.

    Was there a balance in there or not.

    I wonder if it galls Dr. Dederich after his lecture to walk down to the Biolase booth and see all the activity after he tells people that lasers arent needed. It is disappointing to hear of negativity with lasers, but in many instances the people involved in spreading the information have not used lasers at all.

    It is human nature to fear change. Its far more comfortable and safe to stay status quo, but there are benefits of lasers in many areas. Its not a replacement for the handpiece or the scalpel but a nice tool to have in the toolbox.

    Here hoping that someone else will discuss what he said.

    Inquiring minds want to know.

    Well now that you asked? smile.gif
    It was a pretty mild affair. Those that had no clue took it in. Those that are arware of asers just shook their heads and smlied.
    He started off acting like he supported lasers. Then showed CO2 work that had a great deal of char. I was always taught that this was a old technique and we try to avoid char today. He acted like it was routine and acceptable. Then he blasted the Periolase with out saying who they are. Refer to the small sample size. Speculated the bone fill was the result of tramua to the bone from the laser. Then said that there is nothing to show that cemental attachment is stronger then LJE attachment. Then he gave Biolase a future thumbs up . Even approving of calculus removal with the Er.
    In my mind he uses fuzzy logic. There seems to be someting up his sleeve.
    He also is believes that perio sx does not hurt. When will periodontist ever learn that surgions are not all created equal.
    I forget the second speaker. He present some old stuff and was real hot on .96 CO2 lasers for hardtissue. Sounds cool .I don’t think we will see this one under &#36100,000 for a while. He did show SEMS of alloy removal and the presence of free Hg.

    Don’t think we have heard the last form this guy.

    Hey Glenn,
    Missed you in Orlando.
    My review of
    Laser in Dentistry:An Update
    Douglas Dederich DDS
    Head of the Dept of Perio
    LSU School of Dentistry
    Perio trained at U of Pittsburgh
    Had a private practice in Iowa 6 years
    Uses a CO2 laser in his perio practice
    He spoke for an hour, no interaction or questions from the quarter filled room.
    He was on a platform, behind a podium, well away from the crowd. Just kept talking.
    It was a lasers is bad lecture, with the speaker as the authority. “I have used lasers since the early 90s.”
    He showed a couple of his cases, all the gingiva was black and crispy, but that was good. After the burn heals the gingiva heals. Luckily the CO2 damages enough of the nerve endings, so by the time the nerves start to work again at 7-9 days, epithelium is growing back to cover the wound. Therefore no pain during healing.
    There is no CDT code for currettage anymore, therefore currettage should not be done, Therefore Laser currettage is ineffective.
    In California a dental hygienist said she can treat gingivitis with a Diode laser in 8-10 treatments, in Lousianna we can treat gingivitis with a prophy cup and tell the patient to brush and floss.
    Nd:YAG is bad. Deep tissue penetration complicates safety issues w/ respect to collateral damage.
    LANAP has shown histologic evidence of new cementum.
    But no studies show that LANAP regeneration has been superior to a long junctional epithelial attachment with respect to clinical performance.
    Hypothesis of how LANAP works, The Nd:YAG wide pulse width causes heat, this leads to bone necrosis, the marrow cells come back in a couple of months, this stimulates growth hormones, which grows new bone.
    Is it better than a long junctional epithelial repair?
    LANAP is not a curretage procedure.
    Need a large clinical study.
    Next hour Harvey Wigdor DDS
    Clinical Prof/ U of Ill.
    CO2 user, more burned and crispy cases
    His best quote was that you should not be the first one in your neighborhood to buy a laser.
    Reason for purchasing a laser
    1. Hard or soft tissue use
    2.Based on scientific evidence that it is safe for the indications used by practioners
    3. Will be used on a regular basis
    4.Do not purchase a laser without indication, the cost cannot be justified.
    The crowd could not get out fast enough.
    Was an embarrasment for the ADA. BioLase plugged the lecture on all their session literature as a real laser lecture, what a mistake that was.
    I tried to buy a tape, but the filming company didn’t film it,said the ADA did not tell them of the course.
    Sorry you missed it.

    David:  was it confrontational with disagreements from the audience or was it a passive affair with alot of non laser users smiling because someone kept telling them that lasers werent needed.  

    Was there a balance in there or not.

    Inquiring minds want to know.

    Let me try to provide as best I can an objective review of the presentation. There was a small group of ALD members who sat together in the back. The audience was passive and no one confronted the speaker.

    1) The presentation was not wholly negative towards use of lasers in dentistry. Many positive comments were made concerning the use of CO2 lasers for soft tissue surgery and erbium lasers for restorative dentistry. Dr. Dederich stated that he does or has used CO2 lasers for soft tissue surgery. It is my opinion that he made an effort to tone down his presentation when compared to his article in JADA(Feb? 2004).

    2) There was a clear presentation that there is no scientific evidence lasers provide any benefit over traditional modalities for the treatment of periodontitis(diode or Nd:YAG). The histological study by Yukna at LSU was dismissed due to the small sample size(n=6) and because Dr. Dederich stated there is no evidence that cementum mediated new PDL attachment shows any clinical advantage over long junctional epithelium. Dr. Dederich hypothesized that osseous regeneration in the LANAP procedure is the result of initial osseous necrosis caused by the free running pulsed Nd:YAG.

    3) This may be somewhat subjective but my perception was that the 1064nm Nd:YAG was presented as a dangerous wavelength with few clinical uses. For example, Dr. Wigdor(second presenter) showed a case where he had created severe gingival necrosis with an Nd:YAG. Wigdor stated that he had used a Continous Wave Nd:YAG(which I had never heard of). I’m no laser physicist but to me it seemed that if one did not use a pulsed, high peak power, “virtually-never-on” Nd:YAG it would be easy to injure a patient.

    4) Many positives were presented regarding the use of erbium lasers for restorative dentistry. I just found it curious that when it came to indications and usage, all of the Power Point slides had the title “Er,Cr:YSGG”. For objectivity I thought the slides should have had the heading “Erbium” or “Er,Cr:YSGG/Er:YAG”.
